This part of the route follows the Katsura River for most of its length, thereby avoiding both the traffic congestion around Kyoto (which is, after all, a major city) and the suburban sprawl as well. For this reason, a lot of what you'll be cycling through looks just like this - either green riverside scenery or green vegetable gardens. It's a surprisingly pleasant way to travel between two of Kansai's major cities.
Here's the requisite "flower photo" for this route. It's not a rule that each route has to have a flower photo, but it makes no sense to cycle in Japan's flower-filled June and not take at least one photo.
